ABSTRACT:
A basically cross-shaped semiconductor Hall element comprises a pair of current-supplying electrodes as well as a pair of Hall electrodes. The structure includes trapezoidal semiconductor regions extending from the central magneto-sensitive region in both the current-supplying electrode directions to thereby suppress the element temperature rise due to Joule heating. In addition, the contiguous slant edges of the extended trapezoidal portion form an angle .theta. greater than 90.degree. with lateral edges of the central rectangular magneto-sensitive region to thereby suppress the semiconductor noise dependent on the shape itself.
